Brad, gotcha. Thanks. And yes 410 pressures are crazy, I do resi also. Resi is easier!
Tested 152 on my TIFF and it does pick it up
BTW glad to see you back here.

That takes care of the low hanging fruit. Do you have or can you borrow a sniffer?
You can as has been suggested add a couple of ounces of R134 and pressurize the system with nitrogen to 150psi for the sniffer.
I have a leak detector (TIP 5550) but it appears that as a minimum it needs a new tip, I am getting very erratic results. Replacement tips on order, will report back if I still have an issue finding the leak. Thanks for following this thread.

I've seen equalized Low side/High side pressures of 275psi at Lake Havasu AZ at 120 degf ambient,sun-soaked hot engine shut down in Pontiac Formula doing hot soak testing- Black painted car- so yes the evaporator can take it.
